Early results of off-pump coronary artery bypass graft surgery using bilateral internal thoracic artery grafts in octogenarian patients during ten years.
OBJECTIVE
The aim of this study is to review the outcome of OP-CABG using bilateral internal thoracic artery (BITA) grafts in these patients in terms of morbidity and mortality.


METHODS
Retrospective data from consecutive 64 octogenarian patients who underwent this surgery in the period between April 1998 and December 2007 were taken. Demographic data, risk factors, and details of surgical intervention and postoperative complications were analysed.


RESULTS
The mean age was 81.8+/-1.8 years (males=78.1%). Expected mortality calculated by additive EuroSCORE was 7.1+/-1.9%. The mean of left ventricular ejection fraction was 57.3+/-12.3%. Unstable angina was the main presenting symptom in 70.3% of patients and 18.7% had recent acute myocardial infarction. Hospital morbidity and mortality rates were 60.9 and 6.2%, respectively. The most frequent complications were: respiratory (25%) and atrial fibrillation (17.2%). The means of stay in intensive care unit and total hospital stay were 2.4+/-1.9 and 7.6+/-3.7 days, respectively.


CONCLUSIONS
Realizing OP-CABG using BITA grafts had a high rate of postoperative morbidity, however, the mortality rate was low.
